Biobizz's Bio Up pH corrector will correct your pH quickly and naturally, so that your crops can assimilate the nutrients you provide as effectively as possible. Formulated with organic amino acids, you can use it at any time during the growth of your crops.
You'll need to prepare your fertiliser mix, at which point you'll need to measure the pH of your solution. The optimum pH of a solution is between 6.2 and 6.5. If your pH measurement is too low, use Bio Up to raise it. 0.1 ml of Bio Up will increase the pH of your solution by 0.1 point. Increase your pH gradually by mixing your solution well (10 seconds) between two set points until you reach the desired values.
Bio Up is harmless to the microbial life of your soil and crops.
